A Cat's Eye Reflector is a safety device used on roads to enhance visibility at night or in low-light conditions. It consists of a small, raised, reflective element that reflects light from vehicle headlights, making it easier for drivers to see road edges, lane markings, and obstacles. Invented by Percy Shaw in 1934, the Cat's Eye Reflector is typically made of glass or plastic and is embedded in the road surface. Its design allows it to reflect light in multiple directions, improving safety for both drivers and pedestrians by guiding them along the roadway.
